Answer:
2) a. slope = 4/3
2) b. slope = -4
Step-by-step explanation:
The slope of the line that passes through points
and 
is m, given by the slope formula below:

2) a. (30, 32) and (18, 16)




2) b. (4, -26) and (10, -50)




Answer:
list the givens
line SU ≅line UT⇒def of a midpoint
ΔSVU≅ΔTWU⇒SSS
∠SVU≅∠TWU ⇒CPCTC
Step-by-step explanation:
Answer:
The perimeter before is 5+4+5+4=18.
After doubling the length, we do 10+4+10+4=28.
The difference is 10, so the perimeter increases by 10.
